Those nasty little ankle biters cause a lot more harm then pitbulls these days.

Here are some I would recommend (presuming you're looking to do buy and hold rentals):Personal Development: The Science of Getting Rich, Miracle Morning, The 7 Habits of Highly Effective People, Be Obsessed or Be AverageBusiness: The E-Myth, The Millionaire Fastlane, Good to Great, TractionReal Estate: The Millionaire Real Estate Investor, The Advanced Guide to Real Estate Investing,Finding and Funding Great Deals, The Book on Negotiating Real EstateI've also heard good things about How I Turned $1,000 into Five Million in Real Estate in My Spare Time and bought it but have yet to read it (as I'm not in rentals).

Often, the situation where the house is not habitable will trigger certain actions. 

Consider that some of her observations about the house may point to habitability issues that would need to be resolved by you.

Also, I've got a real estate browsing habit and I love houses.

It has been explained to me that this ultimately is an insurance issue that provides a clear path for settlement for the person harmed. 

Today, I'm happy to report I have no mice, the gutter is not doing more harm till it can be properly repaired in the spring, the bathroom and kitchen were repaired for $140, new, qualified tenants are moving in on December 1st under an enforceable lease, and the rent was raised $25/mo.

@Ray Harrell : getting to 75 units is easy: start with 150 units in a F-class neighborhood, then wait a year.At the end of the year, you should have only 75 habitable units left!

One worked for a company and got an esop sellout and got a big check and paid us off the other the family rescued it.everyone else lasted on average 6 months a few went a year or more but that was rare.. we would let them stay until they moved or stopped paying we never gave them a drop dead date.. did not need to.once you get into this end of it you will realize folks that are 3 days from losing their house are very poor credit risks and rental risks.. even though you let them start over their bad habits just surface again.Maybe thats why Oregon made it illegal to rescue and rent back I don't know.but talk about drama holly man.. 

I usually can get used from habitat or salvage yards.
